Or try this puzzle with your engine white to move:

the engine says it is much better for black or?

it is actually a draw

Ba4+ and then you move all the pawns, I did a tactic like this!

Blindfoldm6

At first pawn c4+

After Kc6 Ba4+ only option Rb5 and white is winning!!

Yup!

I think there are multiple solutions to this puzzle. Personally, I prefer 1. d4, though, I know that there are several players who would go 1. e4 or 1. Nf3.

#29 is simply the wrong diagram. Stop posting wrong diagrams!

Yup. White would actually be simply winning after 1. c4+! Kc6 2. Ba4+! Rb5 3. cxb5+ +-

It's not even possible for the black bishop to be on that square.

I let Stockfish 12 run overnight and it finds a mate in 27. Once the pawn queens the search space is quite large. The engine doesn't know that it needs to trap the king to force a move from black, so there is an element to brute force here. Eventually the queen traps the black king, eats through black's pieces, and helps the queen with the mate.

I guess if enough people see this post I will update this with the full solution in a later comment. Have fun! (p.s. I've never tried embedding a puzzle, I hope it worked)

Why does Black's King go c1 and not a2? Us there still # with a2?

After ..Ka2 .Nc3+ white wins on his material superiority since the black pawn does not threaten to promote anymore. The black king survives longer than in the main line but that is irrelevant in endgame studies. What counts is finding clever defenses and not simply delaying the inevitable mate.

Either way white is going to win. Maybe a2 is a shorter mate so c1 prolongs it.

Stockfish 15 NNUE (stronger, 45MB) at depth 50 found mate in 20.

I'll let it run to depth 99 and we can see what the puzzle moves really are.
